I'm trying to interface with a hardware device via the serial port. When I use software like Portmon to see the messages they look like this:

42 21 21 21 21 41 45 21 26 21 29 21 26 59 5F 41 30 21 2B 21 27
42 21 21 21 21 41 47 21 27 21 28 21 27 59 5D 41 32 21 2A 21 28

When I run them thru a hex to ascii converter the commands don't make sense. Are these messages in fact something different than hex? My hope was to see the messages the device is passing and emulate them using c#. What can I do to find out exactly what the messages are?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language.
